Senior Backend Engineer with 7+ years in Java / Kotlin, based in Taipei, Taiwan. I engineer and maintain enterprise-scale Billing & Payment systems and serve as first-line support for their production issues. I also bring hands-on SRE & Cloud skills and build LLM-powered developer tooling.
- Backend: Java, Kotlin, Spring Boot, MySQL (SQL performance tuning), Python, JavaScript / TypeScript; also interested in Go.
- SRE & Cloud: AWS, Docker, Kubernetes, Linux, Prometheus, Grafana — and always leveling up.
- LLM tooling: Claude Code / Codex plugins, MCP servers, persistent dev memory — see below.
- Also: 3+ years of React / Vue frontend exposure and about 8 months of Android development.
Pleased to meet you!
I build LLM-powered tools that make day-to-day engineering faster and safer:
